A 10-ft wide round water trampoline is floating in a pool measuring x ft by x ft. Find a polynomial for the remaining surface area of the pool
Answer
r=5
xsquared-25pi would be the area not covered
r=5
xsquared-25pi would be the area not covered
What would be the area if x was 12 feet? What would be the correct units for your answer?

A 10-ft wide round water trampoline is floating in a pool measuring x ft by x ft. Find a polynomial for the remaining surface area of the pool is given by...
Answer:
r=5
xsquared-25pi would be the area not covered
x^2 -- pi (5^2) ft^2 = x^2 -- 25pi ft^2
Question:
What would be the area if x was 12 feet? What would be the correct units for your answer?
Answer
Since the problem states dimensions are in feet, the answer must be in feet^2.
x^2 = 12*12 = 144 ft^2
x^2 - pi*(5^2) = (144 - 25*pi)ft^2
Since the problem states dimensions are in feet, the answer must be in feet^2.
x^2 = 12*12 = 144 ft^2
x^2 - pi*(5^2) = (144 - 25*pi)ft^2
